Never charge a battery that has frozen: re-
pl ac

e battery! Failure to do so may lead to an
explosion. Note
Use only the terminals in the engine compart-
ment t o c

harge the battery. Replacing the battery
The new battery should have the same speci-
fic
ation
s

(amperage, load and voltage) as the
used battery.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy ›››
page 239.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop.
